Electric cars too quiet? Automakers add real or fake sound to their cabins

Your next car may come with its own soundtrack.

Faced with the utter silence of electric cars – as opposed to the cacophony of engine noise emanating from conventional vehicles – automakers are coming up with novel ways to give them their own distinctive cabin sounds.

It may sound fanciful, but automakers are taking it seriously. BMW just teamed movie music composer Hans Zimmer with its own sound expert, Renzo Vitale, to create lush electronic chords to accompany the acceleration of BMW Vision M Next, an electric concept car, on display at the Los Angeles Auto Show through Dec. 1.

Domestic automakers have also picked up the beat.
